[0027] Batteries are devices that convert chemical energy into electrical energy and are widely used in our daily lives. With the development of the battery industry, companies have increasingly higher requirements for battery production efficiency and yield. A conventional battery includes a battery cell and a case, and generally uses a pole to draw the electricity of the positive electrode of the battery cell from the case, specifically, the pole and the case are isolated by an insulating member, and the pole, the case, and the insulating member are fixedly connected. However, the inventor found that when the pole, the case, and the insulating member are fixed, the insulating member and the battery case are easily rotated relative to each other, which makes the subsequent fixing unstable and reduces the yield of the battery.

[0028] In view of this, the present invention provides a battery comprising a battery cell, a case, a pole base, and a first insulating member, the case having an accommodating cavity in which a battery cell is arranged, the pole base having a main body and a pole, a pole hole being provided in a side wall of the case, the first insulating member being arranged between the case and the main body, the first insulating member being provided with a first positioning hole facing the pole hole, the pole passing through the first positioning hole and the pole hole in sequence, the pole being connected to an electrode tab of the battery cell, the first insulating member being further provided with a third position limiting portion, and a fourth position limiting portion being provided on the outer wall of the case, the third position limiting portion being engaged and connected to the fourth position limiting portion. The battery provided by the present invention has a third position limiting portion on the first insulating member and a fourth position limiting portion on the outer wall of the case that matches the third position limiting portion. When assembling the first insulating member and the battery case, the third position limiting portion on the first insulating member can be engaged and connected to the fourth position limiting portion on the case. As a result, rotation of the first insulating member relative to the battery case can be prevented, improving the production yield and efficiency of the battery.

[0029] FIG. 1 is a schematic diagram of the overall structure of a battery provided by an embodiment of the present invention, FIG. 2 is an exploded view of the battery provided by an embodiment of the present invention, FIG. 3 is a side view of the battery provided by an embodiment of the present invention, FIG. 4 is a cross-sectional view taken along line AA in FIG. 3, FIG. 5 is an enlarged view of line A in FIG. 4, and FIG. 6 is a schematic assembly view of FIG. 5. Please refer to FIGS. 1 to 6. An embodiment of the present invention provides a battery 100, which includes a battery cell 110, a case 120, a pole base 130, and a first insulating member 140, the case 120 having an accommodating cavity in which the battery cell 110 is disposed, the pole base 130 having a main body 131 and a pole 132, a pole hole 121 is provided on a side wall of the case 120, the first insulating member 140 is disposed between the case 120 and the main body 131, and the first insulating member 140 is disposed between the case 120 and the main body 131. The insulating member 140 has a first positioning hole 141 facing the electrode column hole 121, the electrode column 132 passes through the first positioning hole 141 and the electrode column hole 121 in sequence, and the electrode column 132 is connected to the electrode tab of the battery cell 110, the first insulating member 140 is further provided with a third position limiting portion 143, and a fourth position limiting portion 122 is provided on the outer wall of the case 120, and the third position limiting portion 143 is engaged and connected to the fourth position limiting portion 122.

[0030] The battery cell 110 includes a negative electrode made of a negative electrode material, a positive electrode made of a positive electrode material, and a separator separating the positive electrode and the negative electrode. The arrangement of the battery cell 110 may be a winding type, a stacking type, or the like, and this embodiment is not particularly limited thereto.

[0031] The case 120 serves to protect the battery cells 110 therein, and may be formed by joining two parts together to facilitate installation. Stainless steel, which is robust and has excellent corrosion resistance, may be selected as the material for the case 120, but other materials may also be selected for the case 120, and this embodiment is not particularly limited thereto.

[0032] The pole base 130 mainly serves to guide the electricity of the positive electrode of the battery cell 110 to the outside of the case 120 of the battery 100 for easy use. The pole base 130 may be made of a material with good conductivity, such as copper or aluminum, and is not particularly limited in this specification.

[0033] The first insulating member 140 can be made of a material with good insulating properties, such as rubber, resin, etc., and it should be understood that the first insulating member 140 mainly serves to isolate and insulate the pole base 130 and the case 120, and the case 120 is generally used as the negative electrode of the battery 100, that is, the first insulating member 140 is used to isolate the positive electrode and the negative electrode of the battery 100 to ensure that the battery 100 operates normally.

[0034] One assembly method of the pole base 130 is shown in Figures 4 to 6, in which the pole base 130 has a pole 132, a first insulating member 140 has a first positioning hole 141, and a pole hole 121 in the case 120. During assembly, one end of the pole 132 remote from the body 131 can be electrically connected to the positive electrode of the battery cell 110 by sequentially passing through the first positioning hole 141 and the pole hole 121, so that electricity from the positive electrode of the battery cell 110 is led to the outside of the case 120 via the pole 132.

[0035] It should be understood that the first insulating member 140 should isolate the pole base 130 and the case 120. Specifically, as shown in FIG. 5 and FIG. 6, in practice, a flange can be extended around the edge of the first positioning hole 141 toward one side of the case 120. When assembling the first insulating member 140 and the case 120, the flange can be fitted into the pole hole 121 on the case 120, and the pole 132 can be passed through the first positioning hole 141. In this way, the object that comes into contact with the outer wall of the pole 132 is not the inner wall of the pole hole 121 (i.e., the inner wall of the case 120), but the first positioning hole 141 and the inner wall of the flange (i.e., the object that comes into contact is the first insulating member 140). As a result, the pole base 130 is isolated from the case 120 by the first insulating member 140, and the positive and negative poles of the battery 100 do not interfere with each other and can operate normally.

[0036] The battery 100 provided according to the embodiment of the present invention has a third position limiting portion 143 on the first insulating member 140 and a fourth position limiting portion 122 on the outer wall of the case 120 that matches the third position limiting portion 143. When assembling the first insulating member 140 and the case 120 of the battery 100, the third position limiting portion 143 on the first insulating member 140 can be engaged and connected to the fourth position limiting portion 122 on the case 120. As a result, rotation of the first insulating member 140 relative to the case 120 of the battery 100 can be prevented, and the production yield and efficiency of the battery 100 can be improved.

[0037] In the above embodiment, one of the third position limiting portion 143 and the fourth position limiting portion 122 can be a groove, and the other can be a protrusion fitted into the groove. Specifically, as shown in Figures 5 and 6, the third position limiting portion 143 is a protrusion provided on the first insulating member 140 and facing the case 120, and the fourth position limiting portion 122 is a groove provided on the case 120 and away from the battery cell 110.

[0038] Alternatively, the third position limiting portion 143 is a groove provided in the first insulating member 140 and close to the case 120 side, and the fourth position limiting portion 122 is a protrusion provided in the case 120 toward the first insulating member 140 side.

[0039] In the above embodiment, a first position limiting portion 133 is provided on the main body 131, and a second position limiting portion 142 is further provided on the first insulating member 140, and the first position limiting portion 133 is engaged and connected to the second position limiting portion 142. By providing a first position limiting portion 133 on the main body 131 of the pole base 130 and a second position limiting portion 142 matching the first position limiting portion 133 on the first insulating member 140, when assembling the pole base 130 and the first insulating member 140, the pole 132 located on the main body 131 of the pole base 130 passes through the first positioning hole 141 on the first insulating member 140, and at the same time, the first position limiting portion 133 located on the main body 131 of the pole base 130 is engaged and connected to the second position limiting portion 142 on the first insulating member 140. As a result, rotation of the pole base 130 relative to the first insulating member 140 is prevented, thereby improving the production yield and efficiency of the battery 100.

[0040] In actual implementation, one of the first position limiting portion 133 and the second position limiting portion 142 may be a groove, and the other may be a protrusion. Specifically, as shown in Fig. 5 and Fig. 6, the first position limiting portion 133 is a protrusion provided on the main body 131 toward the case 120 side, and the second position limiting portion 142 is a groove provided on the first insulating member 140 away from the case 120 side. Alternatively, the first position limiting portion 133 is a groove provided on the main body 131 close to the case 120 side, and the second position limiting portion 142 is a protrusion provided on the first insulating member 140 toward the case 120 side.

[0041] In the above embodiment, the first position limiting portion 133 may be located on the side of the body 131 facing the battery cell 110 , and the second position limiting portion 142 is provided facing the body 131 .

[0042] In the above embodiment, the first position limiting portion 133 may be multiple, and the multiple first position limiting portions 133 are arranged in parallel on the main body 131. Accordingly, the first insulating member also has multiple second position limiting portions 142, and when the main body 131 of the pole base 130 and the first insulating member 140 are assembled, the multiple first position limiting portions 133 on the main body 131 are simultaneously locked and connected with the multiple second position limiting portions 142 on the first insulating member 140, thereby further preventing the pole base 130 from rotating relative to the first insulating member 140, improving the robustness and reliability of the assembly between the pole base 130 and the first insulating member 140, and improving the production yield of the battery 100.

[0043] 4 to 6, the above embodiment further includes a conductive connector 150, which is located in the case 120 and is connected to the electrode tab of the battery cell 110. Specifically, the conductive connector 150 may be connected between the positive electrode of the battery cell 110 and the electrode pole 132 so as to transmit electricity of the positive electrode of the battery cell 110 to the electrode pole 132 and to draw electricity from the case 120 through the electrode pole 132. By disposing the conductive connector 150, the battery cell 110 and the electrode pole 132 can be connected more firmly.

[0044] In the above embodiment, a gap may be provided between the fourth position limiting portion 122 and the conductive connector 150 to prevent electrical contact between the fourth position limiting portion 122 and the conductive connector 150.

[0045] In the above embodiment, the fourth position limiting portion 122 may be processed into a groove whose bottom portion protrudes toward the inside of the case 120 as shown in FIG. 5 and FIG. 6, or a fifth position limiting portion 162 may be provided on the side of the second insulating member 160 close to the case 120, and the fourth position limiting portion 122 is simultaneously locked and connected to the third position limiting portion 143 and the fifth position limiting portion 162. Of course, other position limiting portions may be provided separately on the inner wall of the case 120 to realize the locking connection with the fifth position limiting portion 162. By providing the fifth position limiting portion 162 so as to be locked and connected to the inner wall of the case 120, it is possible to prevent the second insulating member 160 from rotating relative to the case 120, thereby improving the robustness and reliability of the assembly between the second insulating member 160 and the case 120. The fifth position limiting portion 162 may be a through hole as shown in FIG. 5, or of course, the fifth position limiting portion 162 may be a groove structure, and is not particularly limited in this specification.

[0046] In the above embodiment, the battery may further include a second insulating member 160, which is located inside the case 120, which isolates the case 120 and the conductive connector 150, and which is engaged with the conductive connector 150. The second insulating member 160 mainly isolates the case 120 (negative electrode of the battery 100) from the conductive connector 150 (positive electrode of the battery 100) to ensure that the positive and negative electrodes of the battery 100 do not affect each other. Please refer to FIG. 6 for one assembly method of the conductive connector 150 and the second insulating member 160. The second insulating member 160 and the conductive connector 150 can be provided with a second positioning hole 161 and a third positioning hole 151, respectively, and the pole 132 on the pole base 130 can pass through the first positioning hole 141, the pole hole 121, the second positioning hole 161, and the third positioning hole 151 in sequence.

[0047] In the above embodiment, the sixth position limiting portion 163 may be provided on the side of the second insulating member 160 that is away from the case 120, and the seventh position limiting portion 152 may be provided on the side of the conductive connector 150 that is closer to the second insulating member 160, and the sixth position limiting portion 163 and the seventh position limiting portion 152 may be engaged with each other. The engagement between the sixth position limiting portion 163 and the seventh position limiting portion 152 can prevent the conductive connector 150 from rotating relative to the second insulating member 160, thereby improving the robustness and reliability of the assembly between the conductive connector 150 and the second insulating member 160. Specifically, the sixth position limiting portion 163 may be a protrusion directed toward the conductive connector 150 side as shown in FIG. 5, and the seventh position limiting portion 152 may be a groove directed toward the second insulating member 160 side.

[0048] In the above embodiment, the outer shapes of the first position limiting portion 133, the second position limiting portion 142, the third position limiting portion 143, the fourth position limiting portion 122, the sixth position limiting portion 163, and the seventh position limiting portion 152 may be square, circular, or triangular.

[0049] In the above embodiment, the diameters of the first position limiting portion 133, the second position limiting portion 142, the third position limiting portion 143, the fourth position limiting portion 122, the sixth position limiting portion 163, and the seventh position limiting portion 152 are all greater than 0.5 mm.
